摘要： The difference frequency component between a first fundamental wave of frequency f and a second fundamental wave of frequency f2 is caused to interact with a second harmonic wave, thereby to attain the enhancement of a second harmonic signal, etc., whereby a reflected wave component to be imaged is extracted at a high S/N ratio. By way of example, in a case where the difference frequency component is to appear on the lower frequency side of the second harmonic wave of the first fundamental wave so as to be superposed on this second harmonic wave, the frequencies are set at f2=2.8 f or so. Besides, in a case where the difference frequency component is to appear on the higher frequency side of the second harmonic wave of the first fundamental wave so as to be superposed on this second harmonic wave, the frequencies are set at f2=3.2 f or so.

摘要： A combined wave having a plurality of frequencies and phases is transmitted to each of a plurality of scan lines in at least three rates by alternately inverting a phase by 180°. An obtained echo signal is received for each rate. The echo signals are added by using arbitrary weighting coefficients so that 0 is obtained by using the polarity as the sign. Ultrasonic image data is generated by using a difference tone component contained in the added echo signal.
